Obstructive Sleep Apnea Hypopnea Syndrome CT Measurement Of The Air Passage

Part One Study of Upper Airway Obstructive Sites in Adult OSAHS PatientsObjective:Observe the CT features of upper airway Obstructive Sites in Adult OSAHS Patients, in order to provide help for the clinical diagnosis and treatment.Methods:The study randomly selected48patients with snoring treatment in the Second Affiliated Hospital of Kunming Medical University, And according to the AHI index is divided into24cases of mild and moderate group,24cases of severe group,20cases of healthy people. After all people with Overnight sleep monitoring, all subjects had a quiet breathing in the awake state when the upper airway of Brilliance iCT scanning. Measure all subjects nasopharyngeal space,Retropalatal space Retroglossal space and Epiglottal space, after the district's narrowest plane anteroposterior diameter, transverse diameter, cross-sectional area. Record the measurement results, use of the SPSS17.0statistical software analysis all data.Results:1. Basic information among the three groups, except sleep apnea-hypopnea index (AHI) and body mass index (BMI) was statistically significant, others show no significant difference.2. Compare upper airway parameters of calm breathing state up, The results show that Palate layer cross-sectional area of the posterior region of the minimum area between the control group with mild to moderate group, about the diameter, a minimum area of layer cross-sectional area of the lingual region, about diameter of a significant difference. Layer cross-sectional area of the palate after the zone between the minimum area in the control group and severe group, the cross-sectional area of the transverse diameter, anteroposterior diameter of the lingual region, the transverse diameter, anteroposterior diameter of the epiglottis after zone cross-sectional area of significant difference. Mild to moderate group and severe group a significant difference between the district cross-sectional area of the tongue, epiglottis after zone cross-sectional area. 3.48cases of OSAHS patients with narrow flat distribution show that:3patients in Nasopharyngeal and Retropalatal;9patients in Retropalatal;12patients in retropalatal and retroglossal;8patients in retropalatal and epiglottal;14patients in retropalatal,retroglossal and epiglottal;2patients in all flats. Compare with moderate group, severe group with more people have narrow flats in retroglossal and epiglottal. No significant difference in the nasopharynx and retropalatal.4. In this study, in addition to BMI, and OSAHS severity (AHI) was positively correlated, other measures of statistical difference.Conclusion:1.Upper airway obstruction in OSAHS patients in this group were located in Retropalatal and Retroglossal, and more for more than two and two flat narrow.2. Narrow area of the upper airway changes mainly in the transverse diameter decreases.3. The minimum area in retropalatal can be an important indicator of OSAHS disease diagnosis and severity assessment.4. Obesity is one of the OSAHS incidence factor. PART TWO The correlation between structural characteristics of the upper airway bony and the OSAHS mechanism of39cases of male patients.Objective:Investigate the correlation between structural characteristics of the upper airway bony and the OSAHS mechanism of39cases of male patients by observed male adult OSHAS characteristics of patients with upper airway bony structures.Methods:39cases of male patients OSAHS diagnosed by PSG in Department of Otolaryngology Head and Neck Surgery of The Second Affiliated Hospital of Kunming Medical University was choosed. According to the AHI.divided into19cases of mild to moderate group and20cases of severe group. All of the subjects carried out a CT scan of the upper airway in calm breathing status and the Miiller action. Measuring the length of the hard palate, chin down to the horizontal distance of the spine leading edge of the hyoid bone from center to a level distance under the chin, the hyoid bone the center of the palate, the vertical distance, hyoid center to the submental vertical distance. Record the measurement results, use of the SPSS17.0statistical software analysis all data.Results:1. Palate, length of the longer moderate group of the less severe group, a statistically significant difference; less severe group closer to the level of the spine leading edge under the chin of moderate group, a statistically significant difference; less severe group the moderate group lower hyoid position, the hyoid bone from center to the palate, the vertical distance and the hyoid bone from center to chin vertical distance of two indicators are statistically significant. Hyoid the center of the next level to chin distance was no significant difference.2. Müller action of mild to moderate group than the vertical distance from the hyoid bone center point to the chin in quiet breathing increase; hyoid central point of the Miiller action than quiet breathing in the severe group to the palate, the vertical distance, hyoid bone from center to the submental vertical Distance increases. 3. Retroglossal narrow group and non-narrow retroglossal group comparison between the hyoid bone the center of the horizontal distance under the chin and hyoid bone from center to chin vertical distance between the two was statistically significant, the other parameters did not find differences.4. Each parameter show no Correlation with The OSAHS serious Level (AHI)Conclusion:1.Severe group s airway length longer than the mild to moderate group s.2.Compare with quiet breathing, hyoid position is lower in Muller action.3. Hyoid position participates in a narrow plane of retroglossal.
